Windows 10: Weird Input Lag For A Laptop

This might be a little mind bending .

I had a laptop that suffer input lag from areas that lay above normal heat spots that I have deemed it a keyboard failure as it happened to me before on another laptop and replacing the keyboard solved it . Surprisingly on removing the laptop keyboard and plugging in a new one or a USB one or both the very same keys continued to lag .

Tried the following :
- Disable V-Sync
- Updating All drivers
- Removing All drivers And Sticking With Microsoft's Alternatives
- Defaulting Keyboard and Mouse settings
- Removing All Un-Necessery Accessibility Functions
- Scan for Malware Using Malwarebytes and Comodo
- Resetting Windows
- Using Debloating Scripts And Tools From Here And There

The keys that are lagging are : Arrow Keys 2 3 Q W 9 O

Input lag?

• So I had to install the last fall creator's update because of mandatory security updates. Sometimes I launch tf2 and there's major input lag while other times there isn't. I used to have a solution of reverting to a version before the fall creators update
  but I've tried that recently and I needed to reinstall Windows 10. Another solution was to just restart but I don't want to have to restart my laptop every time I want to play video games. I don't know what's causing the input lag, whether it's because of
  the game or the OS or Logitech Gaming Software (which might not be the issue since I had this issue way before I ever got a logitech mouse). I suspect it's the OS and the fall creator's update. I need a permanent solution to stop this input lag. If anyone
  has one, I would really appreciate it.

 

x1900xtx input lag

Ok I have the same issues with the input lag when using ati tool and the dynamic fan control. I only use ati tool for this feature so my question is this: does the latest version address this issue and if not, can I control the fan speed a different way that wont cause the stupid input lag? The x1900xtx get HOT and I like ati tool, but it is hard to play css when you have input lag for 3-4 seconds every 2 minutes. Please help me ASAP. Does .26 version fix this or what are some suggestions that might eliminate the input lag but still be able to use this great tool? Thanks! Does anyone know if ati tray tool works better in this department?

 

Keyboard input lag (Logitech K270 wireless keyboard, Windows 10 20H2)

Hi there. I've got yet another Windows 10 problem. lol

This time it's my keyboard. I'm using a Logitech K270 wireless keyboard, on Windows 10 Pro 20H2. I have been experiencing keyboard input lag off and on for a couple months now, and I've searched for possible solutions, but none so far have worked. I was hoping you guys could suggest some fixes.

Here's what I've tried, based on the suggestions I've found on the web:

• Updating the keyboard/dongle's drivers (there are no drivers on Logitechs's site, oddly) and firmware. Nope.
• Swapping USB ports. Nada.
• Unplugging any extraneous USB devices. Zilch.
• Checking the batteries. No joy.

As I was typing this it was lagging here and there. It's a bit disconcerting. Anyway... I don't think I missed anything, but if you need more information or diagnostics, lemme know and I'll upload 'em.
